Application filed August 17, 1914. Serial No. 857,135.

To all whom it may concern:

Be it known that we, JOHN W. SHANAHAN and FRANCIS C. MASON, citizens of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Combined Vacuum- Cleaners and Sweepers, of which the following is a specification.

This invention relates to an improved combined vacuum cleaner and brush'carpet sweeper.

The object of this invention is to provide in a carpet sweeper an improved dust pan and dumping means.

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claim.

A structure presenting a preferred embodiment of our invention is fully illustrated in the accompanying drawing, form ing a part of this specification, in which:

Figure I is a side elevation view of our improved combined vacuum cleaner and carpet sweeper, from the left hand side.

Fig. H is an inverted plan view of the same with part of the dust pan at one side broken away to show details.

Fig. III is a detail longitudinal sectional elevation View taken on a line corresponding to the irregular line 3-3 of Fig. ll. a

Fig. IV is an enlarged detail elevation view of a part of the right hand side of the case and parts, showing the position and arrangement of the dump lever and the sweeper carrying wheels.

Fig. V is an enlarged detail view partially in section, taken on a line corresponding to line 5 of Fig. 1V, showing details of the carpet sweeper carrying and driving wheels, and the yielding springs therefor, certain parts being omitted.

Fig. Vii is an enlarged detail perspective view or one of the yielding springs for the carryin wheels or the sweeper.

Fig. 2 H isa detail sectional view, with many parts omitted, taken on a line corresponding to 1ine,7 7 of Fig. 1V, showing details of the dump mechanism and connections for the carpet sweeper part.

Fig. VIII is an enlarged detail view partially in section, taken on a'line corresponding to line 88 of Figs. Ill and VII, snowing details oi the dump operating mechanism.

In the drawing all of the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, we provide our improved combined carpetsweeper and vacuum cleaner with a general casing 1 having heavy sides 2 which serve to carry the remaining parts, the same being propelled by the usual handle 2 Carrying and driving wheels 3 are provided at the rear, mounted on a crank shaft 4: which is connected by pitmen 5 to a series of bellows 7 by the arms 6 thereon.

The vacuum cleaner is similar to that illustrated in our Patent No. 1,222.47? issued April 10, 1917. A dust receptacle box beneath the bellows has a detachable bottom 8 secured in place by upwardly extending screws 9. A detachable nozzle block 10 con taining the passage 11 delivering into the dust collecting receptacle 12, which comprises a framework 13 covered by a fabric 1% and with a discharge door 15 at its inner end. This receptacle is retained by suitable screws 16 through flanges 16 thereon to the nozzle block 10. This nozzle block 10 is attached by a pair of hooks 19 on the plates 1? which are secured-'tcthe ends of the nozzle block 10 Toy the screws 18. Each hook 19 engages a pin 20 on the sideof the case and is operated by a lever 21 pivoted at 22 thereon, all similar to the structure appearing in our said patent, where the details and operation or these parts definitely appear.

Beneath the bottom 8 is disposed a carpet sweeper. This sweeper consists of front and rear bars 23, 23 connected by side bars 23, 23 which constitute the general framework or" the carpet sweeper.

A projection 23 is on the rear of the rear bar 23, through which extends screw 24. Across the front of the carpet sweeper is formed a groove 26 into which extends a flange of sheet metal which is sec lred to the bottom board 8 by upwardly projecting screws 27. The carpet sweeper frame and the main parts can be very readily removed by removing the screw The carrying and driving wheels 28 of the carpet sweeper are resiliently supported in position, revolv-in freely on the outer ends of the rods 29.- lots 30 are formed in the ends 23 of the case to permit these rods to play up and down. Springs 31, shaped somewhat like hair pins, provided with outwardly projecting portions 32 that engage in the case, are hooked at their free ends over side bars 23 by screws 34, as clearly appears.

from a consideration of Figs. II, III and VIII.

A driven friction gear 35 is provided on each end of the brush shaft 36 which carries the brush 37. The wheels 28 are preferably rubber tired and are held yieldingly in engagement with the driven wheel 35 by the springs 31 above referred to. Dust pans 38, of the usual form for such purpose, are supported on pivots 40 at each side of the brush 37 and are provided with up-turned edges 39 which fit into suitable depressions of the front and rear bars 23 of the case. These dust pans 38 are controlled by the dopbled spring connection 41 which is folded on itself and outwardly into an engaging lug 42 at the center, and is turned inwardly at its ends to engage suitable apertures in the ends of the dust pans 38.

An operating lever-43 is pivoted at 44 on the main case and has an upwardly turned lower end 45 which is perforated to receive the lateral projection 42 on the spring connection 41.- A guard and. stop plate 47 is secured to the inside of the sweeper frame by screws 48, and stop lugs 49, 49 thereon limit the lateral movement of the spring connection 41, so that when the lever 43 is memos rocked to one side or. the other, the corresponding dust pan is dumped by the action clearly indicated in Fig. VIII. The spring 41 pushes outwardly and as it is connected to the pans 38 below their pivots 40 the pans are held normally closed by spring pressure. When the spring is rocked the dumping efiect of first one pan and then the other is secured, as shown in Fig. VIII. The upper end of the lever 43 is retained in a suitable guide 50 secured to the side of the carpet sweeper case by screws 51, 51, as clearly appears in Fig. IV. This produces a very compact dump construction which does not cumber the case and at the same time afi'ords an efiective means of dumping the sweepings which may accumulate in the dust pans of the carpet sweeper. I

' The dust receptacle of the vacuum cleaner is removable and can be emptied in the manner indicated in our patent, as is clear from a mere inspection.

Having thus described our invention, what we claim as new and desire to secure by Let-' ters Patent is: I

In a carpet sweeper, the combination of a casing, driving wheels with a suitable sweeper brush journaled in the same, pivoted dust pans supported each side of the said brush, a double spring pivoted to said dust pans below their pivotal support and acting to press the same outwardly and hold the same in closed position, an operating lever pivoted to the casing above and upturned at its lower end to engage the said operating spring, and suitable stop means to
